FIELD OF THE INVENTION
The Present Invention relates to a shock absorbing structure, especially to a shock absorbing structure for the heel of high-heeled footwear.
BACKGROUND OF THE INVENTION
Average females often wore high heels to accommodate their clothes in formal occasions by using the structure of the high heels to make their feet appear to be standing on tiptoe, which would not only make the wearer appear taller, but also make the instep appear to be in a straight line with the lower leg, making the leg line appear longer and the body appearance slender. However, wearing high heels for too long may cause foot pain. To make the wearer be comfortable, a shoe pad is usually placed in the high heel's interior or an elastic buffering part placed under the shoe pad. Yet said shoe pad or elastic buffering part would bounce up and down due to the irregular gravity from the wearer when walking, thus affecting the Heel's stability and cause spraining problems.
As aforementioned disadvantages of prior art, to develop a more ideal and practical structure to satisfy the demand of the consumers has become the main goal and direction for the related manufacturers to research and resolve.
